 ## Known Problems and what to do
 
 1. If the TypeInference does not display any Typehints or Typeselection, restart the IDE including the Extension thus deleting the Cache.
-
+2. Selecting a Generic will Result in a Class-Generic extending Object, wich is not legal in Java. Delete the extends Statement.
+3. Selecting a Generic after another Generic is selected results in illegal Syntax. Delete the newly greated Generic and add the Generic Name and if needet its extension into the other Declaration.
 
 ## Logic
 The Language Server in itself can be used for any Client. The Clients task is to start the Langauge Server and handle the Communication with it.
